Bill O'Reilly laid into Michele Bachmann Wednesday night for comments she made about the president's "lavish" lifestyle in the White House.

During Bachmann's CPAC speech last week, the congresswoman referenced a new book that claimed the president lived a life of excess in the White House and elsewhere at the expense of taxpayers. Bachmann said there were five chefs on Air Force One, two White House movie projectionists and a dog walker. According to CNN's Anderson Cooper, Bachmann got her information from a self-published book by a long-time Republican lobbyist that included no sources.

CNN's Dana Bash approached Bachmann about her comments and the book on Tuesday. Bachmann basically tried to run away from Bash and argued that her speech was about the failures in Benghazi and that everyone needs to stick with the issues. Bash pointed out that Bachmann was the one who brought up Obama's lifestyle in the first place.

O'Reilly seemed to agree with Bash's point. "Now this would be much ado about nothing if not for the fact that trivial attacks are obscuring serious problems in this country," O'Reilly said of Bachmann's speech. "This is a trivial pursuit, and Michele Bachmann made a mistake pursuing it."

O'Reilly said that while he wished Obama would live more like Pope Francis did as a cardinal in Argentina, the president is "entitled to protection, convenience and comfort as he runs the nation." He added:

It’s long past time for partisans, on both the right and the left, to cut the nonsense and look at things clearly. We’ve got huge problems in America and the president’s directly responsible for some of those problems … Michele Bachmann is playing small ball with the president, can’t back up her criticism, and actually trivializes a huge problem: irresponsible spending by the federal government. Two words: not good.
